CONTINUOUS-BURNING- FURNACE 330R BURNTNG ENAMEL WA'RE.

To'aZ'Z whom it mayconcem:

Be it known that we, CHARLES- BIoKMEinn and DANIEL A. LISTON.,"Olt];ZeI1S of the United States, residing at Bellaire, in the county .ofBelmont and State of Ohio, have invented certain new andusefullmprovements in Continuous-Burning Furnaces for Burning Enamel Ware, of whichthe followm'g-is a speclfication. I

This invention relhtesto a new and useful improvement in the manufactureof enameled Ware and it more especially re-' lates to a continuousburning furnace of enamel Ware. I a

The object-of the invention is to produce a furnace, through which thearticles are passed by a continuous movement and with larl'y compressed.Fig. 3 is a transverse section through part of the device. 4 is anenlarged side view of oneof the standards; Fig. 5" and Fig. 6. aredetail views of'parts of the standards. Figs. 7 8, 9-and 1O areperspective views of the blocks used in formingthe top, sides and bottomof the firebox ofthe iiurnace.

In these drawings the numeral 1 designates thefine box or :furnaceproper which is placed upon '-.any suitable foundation. This fire boxhas .a'sbase' 2, consisting of two sides .3 and 4 set apart, so thatthere 1s a space 5 between them the-entire length of the base and openat its ends 6 7. "This I W 2 is m of any-suitable material I '17, Thewidthpf these blocks 10 is in any suitable way so as to act as-.asupporttor the superstructure 'Onthe to s 8 and 9-01 the sides 3and def-thebase 2 1s placed a rseries or line of blocks 10, such as-shown in Fig.9. side by side, the entlre jength of the. bnse2 These blocks 10haveilat flush bottoms 1 1, sides'12'and ends 13.

channels 16 of these blocks 10 are a'lined and form continuous channelsthe entire length of the furnace on ,eech side thereof.' The blocks 10have their outer edges flush with the outer edges of the sides 3 and 4and these blocks project inwardly beyond the inner faces of the vsides 3and 4 and partially over the space 5.- The blocks 10 of one series onone side of the furnace are from theblocks 10 .of the other series onthe other side of the furnace so that there.is a

space 18 between the blocks of the two series, the (space l8 being openat its ends and connecting with the space 5 between the sides 3' and 4;.On top of these blocks 10 at the inner ends of these tops is placed sideby side the furnace-on eachside a series or spaced apart 'k bl k 19,hown/in Fig. 9. These I blocks '19 have in their bottoms 20, the ribs21, adapted to fit into the inner channel of the blocks 10 and flatsurfaces 22 to fit on, v

fiat ribs 15 of .the blocks 10. These'blocks 19 have at their inneredges top projections '23,. The tOPSQfl of these blocks 19 have thedownward and backward curves 25. The

projections 23 may extend slightly beyond the inner edges 26 of theblocks 19. The blocks 19 extend beyond the inner edges of the blocks10., so as to bepartiallyabove the space18. But the projections 23 areto be slightly spaced apart, there being a space 27 between-the oppositeprojections of the two series oi blocks 19.. This space 27 should bejust ahout sufiicient to provide a clear passage f orkthe stems of thestand ands as will be explained. This space 27 opens downwardly into aspace between the lower parts of the .endsof-the blocks 19 and into thespace 18 and the space between the opposite ends of the blocks 19' ofthe twouse me is open at its ends. Back of-the .blocks. 19;, there isplaced endwise npon the ptQPS 14 of the. blocks 10 a series .ofbl mks28; shown in Fig- 8.. These ocks .28 have on their bottoms 29 ribs 30fitting grooves 16 and flat surfaces 31 fit ing flatsurfaces 15 of thetops 14: of the blocks 10. These blocks 28 a so [ha e at their sidesinter-fitting, ribs 32 and .groovesfiii, so that the series of blocks 28on each side of the furnace will beginter: looking .and tight-fitting.These blocks 28 also haze passing through them the two pas- Sages Bland35; the object of which will be explained. These blocks 28 have on theirtops 36, at the inner ends 37, the upwardly 60 M 4 of the base.

verse tapering grooves with two outlets 57 and 58 leading to and passingpartly through the passages 34' and fire box of the furnace.

tapering ribs 38, which form continuous tapering ribs, one on each side,at the tops of these blocks 28, the length of the fire box 1. On theseribs 38 rest the cover blocks 39, shown in Fig. 7 These cover blocks39'have on their under side near their ends 40 trans- 41 adapted to theribs 38 of the side blocks 28, the ribs fitting into said grooves. Attheir middles on the un derside these blocks 39 have dependingtransverse tongues 42. On each side of these tongues the bottom face ofthe blocks 39 has upward and outward curves 43. 0n top these coverblocks have on the ends the bevels 44. r

After the several sets of blocks 10, 19, 28 and 39 are put into placewith their several ribs and grooves interlocked, as illustrated in Fig.3, they are bound together as by end plates 45, with bolts 46 connectingthese plates and passing along the bevels 44. At each corner of thefurnace is placedaven tical angle plate 47 .through the topends 48 ofwhich angle plates the bolts .46 also pass. Attheir lower-ends'49, theseangle plates also secured 'to angle bars 51 embedded transversely in thebase 2 of the fire box 1. These bars 51 extend out each side beyondthebase 2 of the fire bQX 1'. On these bars 51 on each side of the base 2are placed the air-supply pipes 52 and gas-supplypipes 53.

The air-supply pipes 52 have the inducts 54 provided with valves 55 andadated for connection with any air supply underpressure. -The'seair-supply pipes 52 have rising from them a number of educts 56 provided35 in blocks 28, there being one educt for each such block 28. "Thegas-supply pipes 53 are to be connected with any gas supply, natural gasor other. These gas supply pipes 53 have educts 59, as many as there areeducts 56, having outlet pipes 60 and 81 which pass through glands 62and 63 into the outlets 57 and 58 and beyond the inner ends of thelatter into the passages 34 and 35.

The construction described produces a furnace having a chamber above, abase below with spaces connected one with another ver-v tically and openat their ends, and pipes for supplying air and gas to the interior ofthe Into such a device the wareto be enameled is to be continuouslypassed by the construction now to be described. i

An endless track 64 is located in a horizontal plane and so as to passlengthwise through the space 5 between the sides 3 and This track 64 is'supiiiorted uponthe beams 51 at its straight portions and at its curvedends- 66 and 67 upon suitable pillars 68 and 69, which are firmly bracedto support th track and resist strain.

47 are braced by rods 50, which are I 'llhese pillars 68 and 69 risefrom suitable base plates 7.8 and 71, one at each end of the device. 1The base plate 70 is made adjustable'by means of the screw 72 in anyusual way for a belt tightener, so thatthe curved end of the track atthis end may be adjusted to take up slack. Stepped into the base plate71 and rising therefrom is avertical shaft 73 carrying a worm wheel 74engaging a Worm gear "the engine 76; Above the worm wheel 74 thereiskeyed tothe shaft 73 a sprocket wheel 77. Stepped into'the base plate 70and rising therefrom is a vertical shaft 78 to which is keyed Engagingthe teeth of these sprocket wheels 77 and 79 is the endless chain 80,clearly indicated in Fig. 2, as a chain and diagrammatically in Fig. 1.To this chain 80 are secured buggies 81 carrying the standards 82. .Thebuggies 81v consist of a frame 83 havingrjpurnal bearings 84 in pairsinwhich fit the journals 85 of rollers 86, and vertical arms 87 forattachment to the chain 80 and the standards 82. file one side of thearm 87 of thebuggy 81 isse ie ired a plate 88, having two ears 89 bywhich the buggy is fastened to the chain 80.- The vertical arm 87 of thebuggy 81 is made-hollow or withthr'ee'sides and has at 'the top thethreaded 31016.90. Into this hole is securedthe lower end 91 of the stem92 of the standard 82. Toitl e top which rise fingers 95 having thefinely pointed tips 96.

- Operation: The 'apticles to be enameled after preliminary preparationare placed, as I indicatedin Fig. 3, upon the finely pointed tips 96 ofthe'fingers 95. Theengine is put 1 into, operation and through the wormgear mechanism the sprocket wheel 77 moves the chain 80 and with it thebuggies 81, standards 82 and the'supported articles upon the standards.As the track 64 with the chain 80 are located in a horizontal plane, thebuggies with the standards are always in a vertical position. Gas andair are admitted "into the annealing chamber through the outlets 57 and58 and the outlet pipes (i0 and 61, and ignition is made. As theogas andair combined are forced into the annealing chamber, the curved shape ofthe bottom and top of the annealing chamber causes the flames to take acourse indicated by broken lines in Fig. 3. The curved shape to thebottom and top of the annealing chamber is given in the latter instanceby the ole-- pending tongues 42, and in the former instance by theprojections 23. Hence t flames are thrown both on the outside'ane. theinside of the articles to be burned.

Vfith such a device, the heat within the annealing chamber may beretained constant, and the amount and degree applied 7 5 whichreceivespower from another sprocket wheel 79.

of this stem 92 is secured a three-armed frame 93 from the ends 94 ofthe arms of.
